CORINNA  Bookends can be a great time saver after climbing the learning curve. My only wish is that it were more tightly integrated with NeoOffice. You can scan RTF documents created in NeoOffice, but this doesn't allow me very much control. I have started using Mellel mostly due to better integration with Bookends. When your biblio software causes you to change word processors, that's a hint that your biblio software is pretty important.

MARTINBB  On the advice of the developer I have rebuilt the database file. This seems to have solved the problem. My thanks to him for the rapid response.

MARTINBB  Powerbook G4 1.67 GHz 1 GB, OS 10.4.11 latest patches.

I downloaded a trial a couple of days ago and imported 15 references from my Endnote library. Bookends "quit unexpectedly" within minutes and has done so several times when attempting to quit the application normally. More seriously, it has just crashed while I was simply moving the pointer from one item in the menu bar to the next. I have also been trying out Sente, and so far it has been completely stable. I haven't yet used the two applications enough to make any other useful comments about them.

JWILHELM  Bookends is my favorite bibliography software in combination with Mellel.

However, when i downloaded version 10.4.3 the day when it was released all my reference citations showed only thee question marks (= ???).

The has been a "quiet update" meanwhile. Anyone with similar problems should download it again from sonnysoftware's site and it will work.

As it has been noted in the Redler's forum Sente semms to have the same problem with Mellel. Maybe it has something to do with the latter one's update to version 2.6.

KOBADOG  My new macbook pro was a dream...until the day that I discovered that endnote was not compatible with mac office 2008. Never fear....Bookends is here! This program is top notch, and worth every penny. I was easily able to transfer my reference database from endnote (several thousand references), and I've been rolling ever since. I think Bookends is just as cable and more user friendly than endnote, and I would recommend it to anyone and everyone. The tech support is excellent as well.

SAMPLER  I owned BookEnds awhile before I started to seriously use it. So, I decided to compare it to Sente before investing a lot of time in setting up my reference data bases (which I link to Devonthink Pro, by the way.)

I found the user experience with BookEnds far superior to that with Sente. In Sente, the main reference window was badly designed and took up too much room for the amount of information it contained. Switching to a reference's notes required clicking on a tiny tab. Just getting around the reference was frustrating. With BookEnds everything was easy.

After a few hours with each app, I made the decision: I've been happy with BookEnds ever since. Every update contains some new refinement. It's clear that Jon is fine tuning his code.

JOELDI  I have used Bookends for almost two years and now have well over 2,000 references in my database. While I've not used other reference manager programs, I am very impressed with Bookends. It is fast, flexible, and very easy to use. A recent upgrade added the ability to link references so that you know what worked cited another, for example. This allows you to move up and down a "stream" of research very quickly. It's awesome! Updates are frequent, but not too frequent that they are annoying. And... the support is superb! Joel

MACSAILOR  This is one of the must have applications on my MBP. Together with Mellel, Bookend has been a really good friend and helper through my studies. The support from Jon has been outstanding. The application is worth every penny!  
(Version 10.4.1)

CTURNER  I have kept up with Bookends updates for a number of years now. It gets better and better, with lots of customization now that can adapt to the needs of academic researchers. Excellent use of incorporating PDF documents linked to references. A long list of academic/medical servers for downloading references, or you can easily create your own and use the embedded Search for online work. I use Nisus Writer Pro with Bookends and they work very well. Also, Scrivener is a good addition to this workflow. I've found the developer of Bookends to be very responsive and the forums are very active. I have a large database, sub-divided with smart and manual folders and have no problem with speed of input or output.

At this price point and with these features, Bookends is well worth a long look if you need citation and reference help.  
(Version 10.4)

STAR-AFFINITY  Ehhh.... at least on my girlfriends MacBook running Mac OS X 10.5.4 the screen freezes when pressing the + button to zoom the Bookends window to cover the entire screen. Only the arrow cursor can be moved around and force quite doesn't work. It seems a forced shut down is required. I could reproduce this two times.

So, an app can still drag down the entire system. Like back in the 90's! :)

But maybe this is a graphics driver issue? I hear something about a graphics core update coming in 10.5.5...
