They seem like they would make good insulation, and the phone company is giving them away. Do phonebooks make good insulation, and how do they compare to other forms of insulation?

Cellulose loose-fill = R-3 to R-3.8.
Loose fill cellulose – Usually gray and consists of recycled, shredded newspapers, boxes, waste paper, and wood pulp. Cellulose, like rock wool, is denser and more resistant to air flow than fiberglass, but cellulose settles (and therefore, loses effectiveness) much more than fiberglass and rock wool. Persistent moisture can weaken the flame-retardants in cellulose. Dense-pack cellulose is highly resistant to air infiltration and is either installed into an open wall cavity using nets or temporary frames, or is retrofitted into finished walls. However, dense-pack cellulose blocks, but does not permanently seal, bypasses, as a closed-cell foam would. Furthermore, as with batts and blankets, warm, moist air will still pass through, unless there is a near-perfect vapor barrier. Wet-spray cellulose is cellulose mixed with water and adhesive to help the cellulose bind to the inside of open wall cavities, and to make the cellulose more resistant to settling. Wet-spray cellulose must be allowed to dry completely before sealing up the wall with a vapor barrier and drywall. Moist-spray cellulose uses less water to speed up drying time.
That should give you an estimate.
ask a homeless person.they would know.. i think they prefer newspapers though.
