Library Catalog / Call Numbers / Periodicals / World Wide Web / Websites / Online Subject Guides
The Delaware Library Catalog is the library’s online catalog,
and will help you search for books, periodicals, pamphlets and
audiovisual materials. If you want to limit your search to items located at a specific Delaware Tech campus library
only, use the drop down menu for "library" and select that campus library.
You can search the
Delaware Library Catalog using a title or author’s name
if you have that information. If not, you can search using a keyword or subject heading.
In a keyword search, type a word or phrase in the search box and click on the "search" button.
The catalog will look for that word or phrase somewhere in an item's title or subject content.
In a subject search, type a word or phrase in the search box and select "subject" from the drop down
menu and then click search. The catalog will look for that word or phrase in the list of subject headings related to the item.
Some examples of subject headings are listed below.
| QC350 - QC467 | Physics--Optics | |
| TA1501 - TA1820 | Engineering--Applied optics |
PERIODICALS AND PERIODICAL INDEXES
You can find additional information on a topic by researching articles in periodicals, e.g. journals,
magazines or newspapers. To find an article you will look up a specific topic in a periodical index,
which can be in paper format or online. Often online indexes are referred to as “databases.”
In a paper periodical index, articles are listed by subject heading or author’s name.
Consult the Delaware Library Catalog to see if any of the DTCC libraries own the periodical.
Also, you can use an online periodical index to search for articles on a specific topic. Typically,
you will search by typing a keyword, e.g. lasers or optics, and then you will be given a list of articles
related to the keyword. You will have access to the entire article online if “Full Text” is indicated.
If you find an article using an online periodical index,
keep in mind that these are actual periodical articles, not web sites.
If an article you want is not available in paper format or full-text online in the library, consult
with the librarian about requesting it via interlibrary loan.
The periodical indexes listed below may be used to locate articles on or related to lasers or optics.
Use subject headings such as those used in searching the library catalog to locate articles on
lasers or optics in these indexes.
EBSCOhost (online database) - Select Academic Search Premier, MasterFILE Premier and/or
Business Source Elite.
FirstSearch (online database) - Select Business & Economics and/or Engineering & Technology
databases.
Check your library for the availability of the following paper indexes:
Applied Science & Technology
General Science
WORLD WIDE WEB
You may also wish to consult web sites for further information on your topic. To begin your research, go to
Delaware Tech Library Services and follow the link for
Student Resources. You may find the following link useful:
Subject Guides from Other Institutions/Websites (on the Student Resources page)
Another option is to choose the link for Internet/Web Search Engines, also accessible from the Student Resources page. This will lead you to a listing of search engines and directories. Choose one to begin searching the World Wide Web. Ask the library staff for a copy of the handout entitled “Criteria for Web Page Evaluation” to help you evaluate the web sites you find.
