Didn't know what "information" you wanted on the baggage regs - so this is quoted from their website:

Your Baggage

a) Free baggage allowance For international travel (except USA/Canada) on Lufthansa sectors the free baggage allowance in Economy Class is 20 kg, in Business Class 30 kg and in First Class 40 kg. One piece of hand baggage per passenger is allowed on board. Two pieces are permitted in First and Business Class though exceptions may be made, for example, on routes served by small aircraft. Hand baggage must not exceed 55x40x20 cm, or weigh more than 8 kg. One piece should be stowed under the seat in front of you, the other one in the overhead bins. Please take care when opening the bins while the aircraft is airborne or after the landing. On journeys to and from USA, Canada and to Mexico and the Caribbean the free baggage allowance is either as described above, or based on a piece-baggage concept, depending on the point of origin or destination when baggage is checked through. The piece-baggage concept is as follows: 2 pieces of baggage and 1 piece of hand baggage, the dimensions as described above.
b) Additional free baggage items On all international flights the following objects may be taken free of charge as additional hand baggage: 1 coat or wrap, 1 handbag, 1 umbrella or walking stick, 1 small camera, 1 pair of binoculars, a reasonable amount of reading material, baby food for the flight and a baby's carry-cot. Disabled passengers are allowed a wheel-chair in addition to their free baggage allowance, but it must be checked in.
c) Excess baggage Baggage exceeding the free baggage allowance may be transported as excess baggage; the charge is 1,5% of the one-way Economy Class fare per kg, or a set fee for baggage transported on the piece-baggage concept.
d) Special baggage Special baggage charges apply for following items: skis, bicycles, surfboards, windsurfing.
e) Unaccompanied baggage It is also possible to transport baggage which exceeds the free baggage allowance at reduced rates, either as unaccompanied baggage or as air freight. In such cases the baggage should be presented to the Lufthansa freight office at the airport a few days before your departure. The baggage is then subject to the conditions for freight transportation, i. e. the customs and import regulations may differ from those applicable for normal checked baggage transported with the passenger. Please contact the Lufthansa freight department for exact details. There are a number of exceptions to a) and c), but you need enquire at your travel agency or Lufthansa office.
