Digital Library Numbers

What is a Digital Library Number (DLN)?

The DLN is the Digital Library Number assigned to IFAS publications for storage in the EDIS publication management system. It is the filename which appears at the end of the URL for an EDIS publication, and is the number which is used for ordering print-on-demand copies. Some departments have also begun using the DLN as an IFAS Publication Number (IPN) to keep things simple. DLN Prefixes historically have been assigned by IFAS Information Technology during the planning stage of a document, and are not an official indicator of the content of a document or the department of origin. The title footnote on the publication itself should be considered the official source of information about a publication?s origin and history.

To request a DLN for a new publication, use the New DLN Request Form in the Author Section of the EDIS Routing System (login required).

Publications in EDIS may be found with DLN numbers beginning with the following prefixes:

What is an IFAS Publication Number (IPN)?

The IFAS Publication Number is a reference number assigned to official, UF/IFAS supported publications. These publications fall into three general categories:

Fact Sheet:

A brief (usually 8 pages or less) document providing a summary or general overview of one topic or the results of specific activities. They are usually suitable for a general audience.

Fact sheets bear numbers with department prefixes, such as "FCS" for Family, Youth and Community Sciences, "WEC" or "SS-WEC" for Wildlife Ecology and Conservation. When searching by IFAS publication number for a specific fact sheet, enter the prefix and number without dashes or spaces. (e.g., enter "FCS8728SP" for Fact Sheet FCS-8728-Sp: "Buena Nutrici?n para la Salud Oral")

Circular:

Usually longer than Fact Sheets, Circulars provide detailed information about one subject. They are usually suitable for a general audience but may be more technical than a fact sheet.

A Circular may be broken up into multiple fact sheets for display on EDIS, but may also be available in as a single print publication. When searching by IFAS Publication Number for a specific circular, enter "CIR" and then the number without punctuation or spaces. (e.g., enter "CIR879" for Circular 879: "Bobwhite Quail Production")

Bulletin

Bulletins cover a broad subject area and usually contain more technical information. Bulletins are in origin publication of the Agricultural Research Station. When searching by IFAS Publication Number for a specific bulletin, enter "BUL" and then the number without punctuation or spaces. (e.g., enter "BUL846" for Bulletin 846: "Mole Crickets in Florida")

For Sale Publications

Publications available for sale through the IFAS Bookstore have publication numbers beginning with the prefix "SP". When searching by IFAS publication number for a specific for sale publication, enter "SP" and number without dashes or spaces. (e.g., enter "SP" for SP-191: "A Guide to Environmentally Friendly Landscaping: Florida Yards and Neighborhoods Handbook")
