Warning Tips
First, here are some warnings to consider.

Complete or incomplete?
In some cases, the database shows a complete copy of all the existing or known records in a collection. However, in many cases It is important to read any descriptive notes about the collection. If it is incomplete, you will want to study the source again from time to time until you can determine that the project is finished.
 * 1) the collection is still being digitized and uploaded. The uploading is a work in progress.
 * 2) the collection is fully digitized, but only partially indexed. The index is a work in progress.
 * 3) the original collection is still being gathered and will eventually be digitized, uploaded, and indexed. The collection is a work in progress.

Index, index and images, images only?
Some databases show digitized copies of original documents. Some databases are indexes of genealogical data found in documents. Some databases have indexed a collection of documents and linked the index entry to the digitized image of the document named. '''Warning! Every time information is copied into an index, abstract, or extract there is a chance of human error.''' An index may speed up location of a desired record. However, if the indexer misread or mistyped an entry, dependence on an index can result in missing a valuable record or greater details found in an original record. Always study the original source. Look at the digitized copy linked by the index. Browse the original source in the appropriate time period or section where you would expect to find your record, whenever possible.

Other Digitized Books
There are several major efforts to digitize books. Although these projects cover much more than genealogy, some valuable genealogy gems are included. Again, search by all jurisdictions: country, state, count, city, and parish. Search also by surname or keyword. If you find a book mentioned in the FamilySearch catalog that is not digitized by FamilySearch, you can frequently find it in these collections by cutting and pasting the title into the search field.
