The Help page provides detailed information on all the features of the NALDR, including searching, displaying and printing/saving documents. See the drop-down list, below right, for a complete list of topics.

The About NALDR page provides background information on the repository, including an overview of the scope, the system software, and searching options. The page also describes digitizing projects in progress or completed.

The word(s) you enter in the search box will be searched in the full text of all the publications in the repository. The search treats multiple keywords as a phrase unless Boolean operators (and, or, not) are used. See Search Examples below for ways to construct a search.

"a", "and" , "are" , "as" , "at" , "be" , "but" , "by" , "for" , "if" , "in" , "into",

"is" ,"it" ,"no" , "not" , "of" , "on" , "or" , "such", "the" , "to" , "was"

Sort the results by clicking any of the column headings--Author, Title, Source, Year, Volume, and Pages.

Once you select a document from the Search Results list, the Document Display page opens. Only the first page of the document (or the first page with a match if you selected that option back on the search page) displays. The example below shows the first part of the Document Display page.

1. Document/Publication Details
   
   It is particularly important to note the Document/Publication Details when you are viewing an article within a publication because the article itself may not indicate the publication name or volume number on its pages. The Document/Publication Details provide the following fields:
   
   • Author(s)
   • Title = Title of publication or article
   • Source = Title of publication series
   • Year = Year of publication
   • Volume = Volume or issue number
   • Pages = Total pages or page range
   • DocID = Unique identification for the publication; you can enter the DocID in the keyword search field if you want to find a specific publication
   • Publisher = Publisher of the document.
   • Subject = Keywords assigned to describe the subject or focus of the document.
   • Notes = Additional information about the document. For example, there will be a note if the document is very long and has been divided into sections.
   • Link = URL to use if you want to quickly find this document in a future search--just enter the URL in the address window of your browser.
   
   
2. Displaying below:___- indicates which page is being displayed out of the total number of pages in the document. Take note of the total page count before you select "View all Pages." Some documents are very long and can take time to load.

The navigation options and the full text image display follow the Document/Publication Details. Continuing with the same example:

1. Navigation Options are provided at the top and bottom of each document page. They include:



• Previous Page - Moves back one page in the document currently being displayed.
• Next Page - Moves to the next page in the document currently being displayed.
• Zoom In - Enlarges the view of the document page(s) currently being displayed. There are seven sizes (65, 75, 85, 105, 150, 210, 300). Continue to select the Zoom In option until you reach the desired display.
• Zoom Out - Reduces the view of the document page(s) currently being displayed. There are seven sizes (65, 75, 85, 105, 150, 210, 300). Continue to select the Zoom In option until you reach the desired display.
• View All Pages in Browser - Displays the entire document within the browser window. Note the page count before you select this option.
• View as PDF - Converts all the pages to Portable Document Format (PDF) in order to print or save the document. To view PDF files you must have Adobe Acrobat Reader installed on your computer. See the Print Help page for details.
• Previous Page with Match - Moves back to the previous page in the document that contained a match for search terms.
• Next Page with Match - Moves to the next page in the document that contains a match for search terms.
• Previous Document - Moves back one document (as listed in the Search Results).
• Next Document - Moves to the next document (as listed in the Search Results).



2. Document Display
   
   
   • The first page of the document (or the first page that contains a match to the search terms) displays as a Portable Network Graphics (PNG) format file. Portable Network Graphics (PNG) format compresses image files without degrading quality and results in faster loading and display of the image file.
   • Note that the search terms "urban encroachment" are highlighted in yellow. Whenever a match to your search terms is found within the document, the terms will be highlighted.
   • You can use your browser's bookmarking function to bookmark a particular publication so that you can return to it at another time. You might also want to note the DocID of the publication. You can enter the DocID as a keyword search to limit your search to one particular publication file.

To print or save a document on the Document Display page.

1. Make a note of the Document/Publication Details so that you have the basic citation information for the document (source, year, volume, issue). The Document/Publication Details will not be included in the file that you print or save.
   
   
2. Select "View as PDF." The document is converted to a Portable Document Format (PDF) file and displayed in the Adobe Acrobat Reader window. To view PDF files you must have Adobe Acrobat Reader installed on your computer.
   
   
3. Once the document is converted to PDF, select the print or save option in the Adobe Reader window.

1. Note the DocID (located in the Document/Publication Details) for the publication.
2. Open the NALDR Web site using another browser--for example, Internet Explorer (version 6 or higher) --and enter the DocID in the keyword search field.
