yes, and you should as well.
can you read a chess book while playing a correspondence game
Yes the point of correspondence chess is to consult printed and database sources but do not use computers (unless allowed) or consult with friends. Using a book while playing correspondence games is a great way to learn a new opening

Yes...you can use any printed, electronic, or database material, but you can't use a chess engine to analyze a position or get any personal help from another player.

Yes, I often read chess books while playing correspondence games. I need something to do between moves.

Yep, indeed you can, you can even have a pint while you're at it, but you'll come across a lot of people like myself, that never use books or Data Base etc.... all depends how one wants to play!

A pint and a book, what a plan! Much better than mine of limiting myself to only a book. Toss in a little music, a nice spring day, and what a wonderful time to be had.

Yeah, I played with these people. They choose the worst line with the stats like +20%-60%=20% , or follow the game that was lost. No wonder they have a losing position after 16-20 moves. I will never understand why they don't use a possibility to learn an opening that they definitely don't know, or how to play a typical endgame. Not using analysis board I understand, because you want to improve your board vision and calculation skills, but refuse knowledge ???

That's the meaning of Correspondence!
You're meant to; the idea of Correspondence when it first came into thinking was that you are meant to research your moves. In the real world, when it's done by email (or even post!) you can often use computers to analyse the position, even.
On Online Chess you are even allowed to use an opening tree attached to a Fritz, Rybka or suchlike. And I've checked that one with Eric, who's staff.

anything you like
This has been repeated ad-nauseum in the forums here, but I feel the need to point it out here. You can't use anything you like. Books are fine, detabases are fine. Using a computer engine crafty, Rbyka, etc. (except for the opening tree) is NOT ok.

I’d advise against it.
"Any person who commits an offense under US Code, Title 17, Chapter 5, Section 504 subsection c 1-2 shall be imprisoned not more than 1 year, or fined not more than $100,000."

"Could you read a chess book while playing a correspondence game?"
Yes, I recommend that you do.... a large part of correspondence chess is research.

It's the point in Correspondence!
Anyone who blunders a Pawn or more in correspondence shouldn't bother playing it, in my opinion.

What are the rules concerning endgame tablebases? For some reason I have assumed they are not allowed.

What are the rules concerning endgame tablebases? For some reason I have assumed they are not allowed.
Here is a simple presentation of the rules:
Resource |
What is it? |
Is it permitted DURING Turn-Based (and Vote Chess) play? |
Is it permitted DURING LiveChess play? |
Asking another person for advice |
Includes discussing a game-in-progress in the chess.com Forums |
NO* (except during VoteChess - when discussion WITHIN the team is expected) |
NO |
Books |
This is a static resource and involves no calculation of best move. |
YES |
NO |
Chess Engine(chess computer) the move evaluator within e.g. Fritz, ChessMaster, etc. |
Software (or free-standing gadget) that calculates the best move from a given position |
NO (except by agreement of both players, where specifically arranged and must be UNRATED games e.g. in a tournament created for that purpose) |
NO |
Conditional Moves (Pre-Moves) |
Setting your response in advance to one or more of your opponent’s moves |
YES |
YES |
Internet articles; Google searches |
This is a static resource and involves no calculation of best move. |
YES |
NO |
Games Database e.g. chess.com’sGame Explorer |
A database (or collection) of previous games, that is searchable. (It is most useful as an Opening Database - although forVote Chess games, the Explore button takes you directly into Game Explorer at that position). |
YES* (There is some debate about whether DBs containing engine-engine games are permitted). |
NO |
Separate board for analysis e.g. chess.com’s Analysis Board |
|
YES |
NO |
TableBases (Endings Database) |
The results from an analysis of end games (stored in a database) in which the sequence of moves to achieve the best outcome has been calculated |
NO |
NO |

ARTREF: WHAT IS ALLOWED

OK, so I was exaggerating a bit (or maybe a lot!) but you get my meaning. I don't necessarily agree with your comment, cuendillar. Opening knowledge is key; you won't live in a Congress without knowledge of the opening you are playing. But of course endgame manuals are important as well; I love Bobby Fischer's saying:
'Being told to study endgames is like being told not to smoke. Sure it's good advice, but it's the following it that's the hard part.'
And it is true that Judit Polgar once said that before you are an IM, you should study 50% middlegame (mainly tactics; I'm a big fan of tactics), 30% endgame but only 20% opening theory.
So I'm probably wrong, but I spend quite a bit of time not memorising lines, as such, but getting a better understanding of a) opening play in general and b) the openings I play.
