Q: How does a woman go about breaking into the appraisal field?

A: Over the past 10 years, appraising has evolved into a highly skilled type of work. Two of the best known organizations of appraisers are the Society of Real Estate Appraisers and the American Institute of Real Estate Apprasiers.

The 20,000-member Society of Real Estate Appraisers has only 35 women members, but this figure will surely increase rapidly. The American Institute of Real Estate Appraisers, which is a branch of the National Association of Realtors, lists only 20 women among its more than 4,000 members. But this, too, will increase. This does not include the women who are working in the field without professional credentials.

Don't let anyone tell you that appraising is not for women because it's too technical. The American Institute of Real Estate Appraisers is currently sponsoring a course in various cities to encourage more women to ender the field.

In most states it is not necessary to have a license to practice appraising. However, in some states, a broker's license is required. Though some discrimination still exists, in time it will disseminate.

When may he take physical posssession of the property:

Q: How do you take care of old, leather-bound books?

A: Leather bookbindings deteriorate for two reasons. One is lack of oil and the other is acidity. Though it is a good idea to begin treating them with oil when they are new it is too late for you to do that.

If they have not begun to powder, I would suggest using saddle soap, working it in with your fingers. Spread sparingly and rub gently. Wait a few hours and repeat. If the books have begun to powder, sometimes their condition can be improved by using lacquer. Smooth the leather very gently with a fine emery cloth. Then apply oil. You can buy a prepared lacquer in your hardware store. Spray it on the bindings in a thin layer. When it dries, apply a second coat.
