# Questions and Answers

How do I enter multiple authors?

Author names should be separated by a semi-colon, like so: `Brian W. Kernighan; Dennis M. Ritchie`. Don't include the word "and" or anything similar, even if you have 20 authors. If you have the auto-format option checked, then the last name will automatically be shown first for each author.

Other properties which allow multiple values, like "genre" and "keywords", are entered in the same way, with a semi-colon (;) separating each value.

How do I group by a property other than the ones listed in the toolbar?

To allow grouping by a field which doesn't allow grouping by default, check the "Allow Grouping" box for that particular field in the "Collection Fields" dialog.

How do I change which columns are shown?

Right-click on the header bar. You can also drag the headers to re-order the columns, and click on them to sort by that field.

How do I export additional bibtex fields?

&appname; uses the bibtex property to know how to export bibtex fields. If you want to add additional fields to export, such as an abstract, open up the Collection Fields Dialog, and click the Set Properties button. Add a bibtex property with value abstract. Then, when you export to bibtex or bibtexml, that property will be used for the bibtex field name.

What does the name Tellico have to do with anything?

I thought about several other names, a few of which were connected with book collections. However, Tellico can handle more than just books, and besides, this is a hobby, so I chose a neat-sounding (to me) name, one taken from a town close to where I grew up.

What do you include those links to Amazon.com in the search results?

The terms of agreement for accessing the Amazon.com Web Services require all images pulled from the service to be linked back to Amazon.com, as well as an additional link. The Amazon.com associate's ID is necessarily included, so any referral payments are duly collected.

Why don't you use a real database?

Part of the reason I started &appname; was to learn C++. I didn't know SQL at the time, and at the moment, I only have a faint knowledge of how to use it. Simply put, &appname; didn't start out as a relational database, and that won't change until sometime in the future when I get around to learning SQL and have the time and motivation to change the data model.

Of course, anyone is welcome to make any changes they want to with the source code.
