Enter your keywords separated by spaces and click Search. Records that match your search terms will be returned.

• Using parentheses to clarify the logic, you can create complex queries with OR and NOT (here capital letters are required, otherwise they will be treated as keyword terms).
• You can also use double-quotes to specify terms that should be treated as one.
• Lastly, you can include the terms image(s) or type(s) to find records that have images or that are type specimens.

Note that searching for common (vernacular) names may not yield the expected results. Associating common names with specimen records is a work in progress.

Keyword search example: cyprinodon (coahuila OR "nuevo leon")

Use the By Field search to find specimen data that match values in specific database fields. Enter a value or choose one from the dropdown lists.

• Click the Search button to initiate a search. Clear resets all fields.
• Some lists are linked, so for example, choosing a Country narrows the choices for Province/State/Territory, and District/County. Dropdown choices also narrow as you type, for example, typing cypr in the Family field might narrow the choice to Cyprinodontidae.
• Note that the Province/State dropdown is populated only after you have chosen a Country. You can type a Province/State without selecting a Country.
• Check Only Records with Images if you want to restrict the search to records with multimedia content.
• You will receive a warning when you enter invalid information in the text fields. For example, Catalog Numbers are composed strictly of letters and numbers; other characters will raise a warning.

The results of your searches can be displayed in Grid (a sortable, customizable table) or Gallery View (best for reviewing images). Use the Switch button to cycle between these views.

• You can choose whether to display 5, 10, 20, 50, or 100 records at a time.

In Grid View:

• You can choose the columns to display from any column's dropdown menu (mouse into a column header and click the dropdown icon). Under Columns, click the name to display or hide the field (you do not need to click the checkbox specifically).
• You can drag a column header to change its order of appearance in the grid.
• You can also drag the edge of a column to make it wider or narrower.
• Click in the expansion () column to view the full record.

In Gallery View:

• Click the image to view the full record.

See Exporting Results for information on downloading results to, for example, Excel or Google Earth.

Open the full collection record by clicking the expansion button () in Grid View, or anywhere within the image frame in Gallery View. Inverse expansion buttons () indicate records with multimedia (typically, images).

• In the Record window, metadata for the multimedia content is available when you mouseover the thumbnail.
• Clicking the thumbnail opens the content in your browser or other appropriate application.
• Record windows may be resized or moved within the browser window.
• You may have up to ten Record windows open at any one time.

Sort results in Grid View by clicking the column header (or by choosing Sort from the column's dropdown menu).

• Sort on multiple columns by consecutively sorting columns in reverse order. For example, to view results sorted by Country and Province/State, first sort by Province/State and then sort again by Country.
• For any column you can choose to sort in Ascending or Descending order.

Export all or selected results by clicking the Export Results as CSV button in the bottom toolbar in Grid, or Gallery View.

• Select individual records for Export by checking the export selection box (along the left edge of the Grid View grid).
• Clear all selections with the Clear Selections button in the bottom toolbar.
• Results are exported as comma-separated-values, one record per line, which can be saved to disk or opened directly with applications such as Microsoft Excel.

You can also export all or selected results to a KML file for viewing with Google Earth or other KML viewers, by clicking the Export as KML button. This button is grayed when all or selected results lack latitude/longitude values.

To create a link to specific records at NMNH provide the appropriate unit and querystring to:

http://collections.mnh.si.edu/search/UNIT/?QUERYSTRING

where UNIT is:

• anth, birds, botany, ento, fishes, herps, iz, mammals, ms, or paleo

and QUERYSTRING is (use a plus-sign to separate words):

• One or more CATALOG NUMBERS, e.g.
  • mammals/?nb=98312+A884
  • paleo/?nb=v4734
• One or more BARCODES, e.g.
  • anth/?bc=e2457-0
  • botany/?bc=00007842+00588979
• The NAME of a TYPE specimen, e.g.:
  • birds/?qt=corvus+corax
  • herps/?qt=bottae
  • paleo/?qt=canis+edwardii
• The NAME of a specimen or object, e.g.:
  • anth/?qn=woven+basket
  • ento/?qn=musca+domestica
  • fishes/?qn=ablabys
  • ms/?qn=new+concord
• The NAME (qn) and/or TYPE STATUS (qt) of a specimen, and/or its COLLECTOR (co), and/or the COLLECTION (cn) it is part of, e.g.:
  • iz/?q=qn+torre+bartsch+qt+holotype+cn+henderson+collection+co+webb
  (Holotypes whose name includes Torre and Bartsch collected by Webb and part of the Henderson Collection)
• To open the Collections Search to a specific search tab, e.g.
  • iz/?ti=1 (Invertebrate Zoology Keywords Search)
  • mammals/?ti=3 (Mammals Whale Collection Search)
  Tabs are numbered left to right, beginning with zero.

There are ways to speed up your queries (or slow them down!) and to find specific information.

• The more specific you make your queries the faster they will execute. Using more, rather than fewer, terms will very likely speed up your search.
• These following special characters modify the interpretation of search terms (use with as many other terms as possible to avoid slowing your search):
  • * matches any number of characters, e.g. *pseudo*
  • ? matches a single character, e.g. young?lus frank?
  • ! negates the presence of a term, e.g. !new
  • ~ matches all terms with the given stem, e.g. ~spear for spear, spears, spearing, etc.
  • = match is case-sensitive, e.g. =Paris
• Query results are typically limited to 5000 records. Avoid general queries, when you can, that are likely to bring back very large numbers of records, e.g. searching for perciformes.
• Long running queries are automatically terminated, with no results returned.
