About EPRR

Welcome to the Los Alamos National Laboratory Electronic Public Reading Room

The Electronic Public Reading Room (EPRR) contains Los Alamos National Laboratory documents required for compliance with environmental regulations and permits. Other documents that deal with environmental issues are included in EPRR.


The documents are browsable by category and regulatory type. Documents added within the last 30 days are viewable via a "New Records in EPRR" link. Documents may be searched using subjects, authors, title, full text or document numbers.

Regulatory type and regulatory agency have been assigned to records starting in 2011.

Full text searching is a compliance requirement beginning in 2011. Full text extraction for the older documents is also available.

EPRR is updated as new documents are received.


This Electronic Reading Room has many options for downloading documents and receiving notifications when new documents appear. For details, see the "Help" section.


If you have questions, please contact us at 505-667-0216 or envoutreach@lanl.gov.


FAQs

Larger PDFs are displaying an error.

  • The problem appears to be with the adobe9 plugin for Firefox and large PDFs. A workaround (other than using IE or Right-click, save-as) is to go: Tools>Options>Applicatons>Select Adobe and reassociate the Adobe Acrobat Document content type from 'Use Adobe Acrobat (in Firefox) to Use Adobe Acrobat (default). This will allow the pdf to be loaded into an instance of Acrobat running on it's own, rather than in FF.

  • If these suggestions are unsuccessful, please send an email to the Research Library with details, such as report number, author, and title. We will send you a copy of the PDF.

Searching

Basic Search


Enter terms into the box and click the go button. Terms will be searched in all fields and years and in the full-text of the item (if full-text is available).


  remediation
  {finds remediation in any field or full-text}
  rogers
  {finds rogers in any field, e.g. rogers in the author or title or in the full-text}

AND is assumed between multiple terms. The following searches are equivalent:


  groundwater rogers
  {finds groundwater AND rogers in any field in the record and in the full-text}
  groundwater AND rogers
  {finds groundwater AND rogers in any field in the record and in the full-text}

Combine terms with {AND, OR, NOT}, entered in UPPERCASE, to function as Boolean operators. (If they are entered in lowercase {and, or, not}, they are treated as search terms and may be stopwords depending on the index.)


  canyon NOT pajarito
  {finds canyon anywhere in the record but pajarito must not be in the record}
  canyon not pajarito
  {same as entering: canyon AND pajarito - "not" is a stopword so it is ignored and the remaining search terms are nevada AND test}

To search terms as a phrase, enter terms in double quotes " ". This preserves the adjacency and order of words in the phrase, but NOT necessarily the exact form of each term.


  "monitoring well"
  {finds records with: "monitoring well" OR "monitoring wells"}

Once you are familiar with the query syntax, you can perform any search {simple or complex} from the Basic Search Tab. To specify the field context in which the search term{s} must appear, prefix them with the Field / Index:


  Author author:
  Category subjects:
  Full Text fulltext:
  Number number:
  Title title:

To apply the same field context for multiple terms, enclose them in parens ( ). To specify a phrase and word order, enclose the terms in double quotes " ".


  author:simmons NOT title:("groundwater data" OR "conversion summary report" OR "monitoring report"
  author:simmons AND title:("conversion summary report" NOT response)

Boolean Operators


When multiple terms are entered without Boolean operators, AND is assumed.


Combine terms and/or phrases with specific logic and order by using the Boolean operators AND, OR, NOT, + and - :


AND narrows search to records where all terms exist water AND release
OR broadens search to records that include either term water OR release
NOT narrows by excluding records where the term exists water NOT release
+ specifies that the term after it must exist water +release
- specifies that the term after it must not exist water -release

The terms AND, OR, NOT must be entered in UPPERCASE to function as Boolean operators.{If they are entered in lowercase {and, or, not}, then they are treated as search terms and may be stopwords depending on the index.}


Use parens ( ) to group terms to control the order of more than one Boolean operator.


(response OR notice) NOT plan
{finds records where 'response' or 'notice' are anywhere in the record and 'plan' is not in the record}

Boolean logic can also be applied with specific Field/Index commands, along with quotes for phrases and parens for nesting:


title:((progress report) NOT monthly)
{finds records where 'progress' and 'report' must be in the title and 'monthly' is not in the title}

Fielded Search


Use the Fielded Search tab to specify the context in which search term{s} must appear.


Select the field/index from the pull-down list to indicate where the term{s} should appear, and then enter the term{s} in the box.


  • Author (e.g. author, editor, institution/affiliation, sponsor, patent holder, etc.)
  • Subjects
  • Full-Text
  • Number
  • Title (title of the item)

Use the pull-down list to the right of the search term box to specify what Boolean operator (AND, OR, NOT) to apply between fields.


AND finds records where both terms appear
OR finds records where one or both terms appear
NOT finds records where the first term appears but not the second

Fields / Indexes


To perform a context-sensitive search, specify a field or index. You can search any field by using the query syntax as indicated in the table below.


Note: The field is only valid for the term that it directly precedes.
          To find multiple terms in the same field, enclose the terms in parens ( ).
         To find a phrase in a specific field, enclose the phrase in quotes “ ”

Fuzzy Search


To do a fuzzy search, use the tilde ~ symbol at the end of a search term.


title:remediation~


In fuzzy searches, an additional (optional) parameter can be used to specify the required similarity. The value of this parameter is between 0 and 1. Only terms with a higher similarity are matched when the parameter value is closer to 1. The default is 0.5 if a parameter is not given.


author:hickmott~ = author:hickmott~0.5


{finds HICKMOTT, DHICKMOTT, HKKMOTT, HICKROOTT}


author:hickmott~0.9


{finds HICKMOTT}


Fuzzy searching is supported based on the Levenshtein Distance, or Edit Distance algorithm.



Normalization


Embedded periods in search strings are converted to spaces. Embedded spaces are preserved.


  • ‘20.6’ is searched as ‘20 6’

Embedded hyphens are stripped and ignored.


  • “16-206” is searched as “16206”

For alpha-numerical strings, the alpha portion is treated as a separate word from the numerical portion.


 

TA-16-206 = “TA 16206”
cobalt-60 = cobalt60”
LA-SMA-2 = ”lasma 2”
Am241 = Am-241”


Report numbers:


LA-UR-08-05847 can be searched as:

LA-UR-08-05847
LAUR0805847
laur0805847
“la ur 08 05847”
“LA UR 08 05847”


Proximity Search


Finding terms within a specific distance from each other is also supported. Use the tilde ~ symbol at the end of a phrase (terms enclosed in double quotes) followed by a number to specify the maximum distance between terms.


title:"water monitoring"~5


{finds the words ‘water’ and ‘monitoring’ within 5 words of each other in any order in the title field}


Relevancy Matching / Boosting a Term


By default, results are sorted by relevance. The uniqueness of each term is taken into account when determining the relevance score. Boosting allows you to control the relevance of a document by weighting specific terms higher than others in a query.


To boost the relevance of a specific term, add the caret symbol '^' followed by a boost factor (a number) at the end of the term. By default, the boost factor is 1. The boost factor must be a positive number, but it can be less than 1 (e.g. 0.5). The higher the boost factor, the more relevant the term will be.


Example:


Compare the order of results for the following:


canyon AND (pajarito^10 OR pueblo)

{entries containing "pajarito" appear before those containing "pueblo"}


canyon AND (pajarito OR pueblo^10)

{entries containing "pueblo" appear before those containing "pajarito"}

Boosting can also be applied to phrase terms.


Stemming


Automatic stemming is limited to singular/plural forms of English language words.


"pueblo canyon"

{finds records with: "pueblo canyon" AND "pueblo canyons"


Truncation / Wildcards


Single and multiple character wildcards can be used within or at the end of single terms but not within phrase queries (the double quotes that surround phrase queries negate the wildcard).


The single character wildcard symbol ? can be used within or at the end of a string.


sm?th

{finds SMITH, SMYTH, SMYTHE}


cibol?

{finds 'cibola' or 'cibolo'}


To substitute or truncate for multiple letters, use *:

hol*kamp

{finds HOLTKAMP, HOLZENKAMP}


author:kud*

{finds author names that begin with "kud" (e.g. KUDRICK, KUDRYAVTSEV, KUDIN, KUDIMA, etc.}

Wildcards cannot be used as the first character of a search term or phrase.


Search Filters


Search filters summarize the frequency of a specific type of value within a result set. The primary use of a facet is to drill down into the results.


Facets are automatically generated for each search query:


  • Publication Year
  • Report Series
  • Author
  • Category
  • Regulatory Agency
  • Regulatory Type
  • Document Type

Up to five links automatically display for each facet. Additional links for a facet can be viewed by clicking on Show more .... Expanded facets can be minimized by clicking on Show less.... Use the [-] and [+] preceding the Facet name to collapse the facet, or return it to its original view.


By clicking a facet link, the search results can be narrowed by its value (e.g. Publication Year = 1999). Each facet link also displays the number of records that match the facet value (e.g. Publication Date, 1999 (508)).


Use facets to:


  • Refine or narrow the original search with predefined limits (Publication Year, Document Type, or Author)
  • Continue to drill down in a results set by selecting additional facets

Sorting Results


Search results are sorted by relevance by default, so that the records deemed to be more relevant to your search terms are displayed first.


Results can also be sorted by year: click the year link at the top of the results list. Results will then display by most recent first.
