Actually, it was a project of the publisher, as far as I know. The publisher wanted to do it, and the Church agreed to cooperate with him in doing it.
That is true. There is heavy church involvement, including several General Authorities. BYU resources were set aside for the project. Here is a review from the FARMS website:

And here is a quote from that review by John Gee:
““The encyclopedia, however, was initially designed with nonmembers in mind. Because so many faithful intelligent members (along with a very few nonmembers) contributed so much of their time for generally meager monetary rewards, the
encyclopedia, though hardly either official (see p. 1:lxii) or exhaustive, is authoritative.”” emphasis mine
That is a good book. Most of the articles that are in it are very well written. But there are also some theological errors in it. I wouldn’t describe it as, “as close to an authoritative source of Mormon doctrine as is possible to find”. I would reserve that description for the standard works of the Church.
Mr. Gee details several of the errors he finds in the Encyclopedia.
Alma147 said that about it being authoritative, and he evidently is not alone in that opinion, it being also shared by the FARMS reviewer.
I’m not trying to argue the merit or lack of merit of the Encyclopedia of Mormonism. I just think that it is worth noting that the LDS church doesn’t have a catechism in which its teachings are laid out in order. This makes it very difficult for anyone, Mormon or otherwise, to establish what is or is not Mormon Doctrine. Even the McConkie book by that name has been disavowed by many Mormons, including yourself, as I recall.
This means that there is a wide field of doctrinal opinion, and that Mormons are allowed to “have their doctrine and deny it too.”
It is not as big a divide as in some other established religions; but Mormons can disagree about doctrine like people of other faiths can.
Those “other faiths” would not include the Catholic Church. Father Hardon’s excellent Catholic Dictionary defines Doctrine, in part, this way:
““Doctrine: Any truth taught by the Church as necessary for acceptance by the faithful. … what makes it doctrine is that the Church authority teaches that it is to be believed.””
So, while Mormons may be able to believe whatever they WANT to believe as doctrine, Catholics are a good deal more systematic about what is, and what is not, doctrine. It is all laid out very nicely in an orderly fashion, so that it can be read and understood, and cannot be denied by an apologist who wants or needs to hide from it.
