If I could only afford one anatomy book, I would choose Schider's Atlas of Anatomy for Artists. It includes plates from many different artists, so you get to see how different draftsmen "see" the same shapes. It's awesome.
And it's under $10.
I was once on the receiving end of a critique so savagely nasty, I marched straight out of class to the office and changed my major (sketchbook).
Ok here's the deal, i wanted to buy Bridgman's Life drawing and his anatomy book, but that doesnt add up to 25, what means i cant get free delivery.
So i can buy something like Loomis igure drawing + Constructive anatomy or Life Drawing + Loomis.
What do you think ?
Up to you and your math.
There are several books mentioned in this thread you can pick from and come up with something. I mentioned not getting Constructive anatomy first because while neat, I think it's best to read the Green book Life Drawing first before trying to look at the figure in parts - which is what constructive anatomy does.
However, this is just an suggestion based on experience, because I got Constructive Anatomy before I got the Life Drawing book, and realized Life Drawing was better to start with first.
In the end however, it's all up to you, you're going to probably go through more books, and there are these book rental places too called "libraries" and you may find those books there. Though all the book ordering in the world, won't make you a better artist - lots of practice will So just pick a book or two and order more down the line.
Well if you work in front of a computer like me you can get all of loomis's books here for free http://alexhays.com/loomis/
If you look around the internet a bit you can probably find bridgemans stuff for free as well.
Both loomis and bridgeman are long dead so I really don't see the point in paying for their stuff.
Many of Bridgman's books are indeed out of copyright, those that are can be found on sites like Project Gutenberg, Archive.org, or Google Books. The Loomis books are not. Loomis is a particular case, the books were initially scanned and put up online because they were out of print and only available used for outrageous prices. Many attempts were made to reprint them, but because of various legal difficulties all were unsuccessful until the current Titan Books editions, which are both beautifully done and relatively cheap. Since this is what everybody has wanted for so long, the proper, practical, and moral thing to do is to buy the reprints, whether or not you already have the PDF versions, to encourage Titan to keeps the books they've already reprinted available, and to reprint the ones they haven't yet gotten to (Creative Illustration!).
